INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MTM-1400 multimode mini video transmitter. Please take
a few minutes to read these installation instructions in order to obtain the maximum performance from this
product.
FUNCTIONAL DESCRIPTION
The MTM-1400 operates as half of a transmitter / receiver pair for the transmission of baseband NTSC,
PAL, RS170, or RS343 video signals with bi-directional RS422 data. It is designed to operate with the
MRM-1400 or RRM-1400 video receiver over a single multimode fiber optic cable.
The MTM-1400 converts a single video input and a single RS422 input into an optical output using a 1300
nm wavelength source. The MTM-1400 also converts an optical input signal returning on the same fiber into
a RS422 output signal using an 850 nm wavelength detector. The M1400 Series product is designed to
operate over an optical loss budget range of 0 to 12 dB. The MTM-1400 operates on 50 um or 62.5 um
multimode fiber. Refer to the data sheets for detailed performance specifications.
This unit is contained in a compact and rugged aluminum housing with internal dc voltage regulation. The
detachable terminal block and LED indicators provide for easy installation and monitoring of video and dc
power.
The MTM-1400 is designed for mounting as a modular stand alone unit. For a rack mounted version please
see the RTM-1400.
INSTALLATION
THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND SHOULD
CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL CODES.
Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing on the next
page for mounting dimensions. Be sure to allow sufficient room for the required minimum bend radius of
the fiber cable used.
POWER SOURCE
THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY.
The unit requires a +12VDC power source for proper operation. The DC input is diode protected. In the
USA and in Canada an American Fibertek PS-12 is supplied with this unit. The negative side of the power
input is directly connected to ground. ANSI/NFPA 70 Class 2 wiring is recommended.
